Pruning; It is best to prune apricot trees in late winter or early spring when the new leaves and flowers begin to show. Cut off the thinner branches with narrow crotches (ie; those flimsy branches that grow more up than outwards) . In addition, apricots should be thinned out once the fruit sets in, this is because a too heavily laden tree will produce smaller fruits than normal.
Soil depth; apricots require deep soil to grow well, a depth of 1,5 metres is recommended
Care; It is best to protect apricot trees from excessive winds, and ensure that you plant them in an area that receives little frost as they are susceptible to late frost. Painting the bottom of the trunk with a non-caustic, quick-drying paint can help reduce the effects of extreme cold and/or harsh sunlight as they are heat sensitive.
